Over the past few Olympics, NBC has shown more live coverage over the Internet than it has on TV. For the upcoming Winter Games, Comcast’s Xfinity TV subscribers will be able to tap the breadth of that online coverage on their big screens.
For the first time, subscribers who use Comcast Corp.’s latest-generation X1 video set-top box will be able to access content that had once been ‘‘digital only.’’
That includes use of the NBC Sports Live Extra app on big-screen TVs. This year, the app will include a buffed-up version of a live program called ‘‘Gold Zone.’’ It will cut in and out of medal events and recap highlights. This time, it will also have hosts and a studio, similar to football’s NFL RedZone channel. Full story for BostonGlobe.com subscribers.
